Magmar is a next-generation infrastructure platform offering developer-friendly tools for building ERC‑4337-native smart accounts and censorship-resistant file storage. With features like gasless transactions, seamless onboarding, bundled paymasters, and Filecoin-powered encrypted storage, Magmar helps developers in DeFi, Real-World Assets (RWA), and DePIN create dApps with smooth user experiences, scalable foundations, and strong security.
Ethereum’s shift toward account abstraction via ERC‑4337 is designed to replace externally owned accounts (EOAs) with smart accounts that support social recovery, gas sponsorship, and custom logic. But implementing the full ERC‑4337 stack can be complex.
Magmar simplifies the process by providing:
The tools reduce backend complexity and help developers launch smart account-based apps more efficiently.
One of the main barriers to Web3 adoption is the need for users to hold ETH and manually pay for gas fees. Magmar supports sponsored (gasless) transactions through integrated Paymaster modules, allowing developers to cover transaction costs on behalf of users.
Paymasters can be configured to:
These capabilities unlock frictionless user flows, such as:
Removing the need for upfront token holdings or gas management helps Web3 applications deliver smoother user experiences while preserving decentralization and user control.
Magmar’s File Vault provides a streamlined solution for integrating decentralized file storage directly into smart account workflows. Built using Filecoin and Lighthouse, the system allows developers to store encrypted files in association with a smart account through a single upfront payment, avoiding the need for ongoing subscriptions or recurring fees.
This model is particularly useful for applications where persistent and permissioned data storage is critical. For example, real-world asset (RWA) platforms can use File Vault to attach documents such as identity proofs or licensing information to user-controlled wallets. AI-focused projects may store training datasets that need to be publicly verifiable or user-accessible on-chain. Similarly, NFT applications can store associated media files or metadata off-chain while maintaining decentralized ownership links. DAOs may use the system to persistently archive proposals, governance documents, or contributor records in a transparent and censorship-resistant format.
Because the files are linked to the smart account rather than a centralized storage provider, access control remains fully decentralized. Encryption and retrieval are handled in a way that preserves user sovereignty, and the underlying Filecoin network ensures long-term storage through its distributed architecture. Even if Magmar's infrastructure becomes unavailable, stored data remains accessible through Filecoin, reducing reliance on any single point of failure.
Magmar offers a comprehensive SDK stack that enables developers to build and deploy smart account systems without needing to manage the underlying infrastructure themselves. The toolkit includes several key components designed to streamline development:
The SDK is built to integrate smoothly with modern frontend frameworks, requiring minimal setup while maintaining flexibility. Developers retain full control over the user interface, access control logic, gas policies, and paymaster funding sources, while leveraging Magmar’s managed services for complex backend operations such as bundling and simulation.
Magmar’s smart account infrastructure and decentralized file storage system are well-suited for a wide range of use cases across the Web3 ecosystem. The platform supports applications that require intuitive user experiences combined with secure, permissioned access to sensitive data.
The overall architecture enables projects to onboard users, enforce access controls, and manage critical data through a unified, decentralized framework — eliminating the need to build and maintain complex backend systems.
Magmar offers native compatibility with the ERC‑4337 standard, enabling seamless integration with smart wallet frameworks, simulation APIs, and bundler infrastructure. Developers using Magmar are not tied to a specific vendor and can configure the stack according to their project’s requirements — whether that involves switching bundlers, deploying alternative paymasters, or routing transactions through custom relays.
Additional supported features include:
The modular architecture allows development teams to maintain agility while ensuring transparency, auditability, and resistance to censorship.
Magmar has locked its liquidity using UNCX, adding an extra layer of security and transparency to its token ecosystem. This move helps protect the project’s native assets and paymaster funds from unexpected withdrawals, while giving the community full visibility into the locked amounts and timelines.
Using UNCX ensures that liquidity is verifiably secured through audited smart contracts, reinforcing trust with both users and partners. It’s a clear signal of Magmar’s commitment to long-term stability and responsible project management.

Magmar addresses some of the most persistent challenges in Web3 development — including complex onboarding, gas management, and unreliable data storage. Through its smart account infrastructure, Magmar abstracts away many of the technical barriers users typically face, such as needing to hold ETH or manage private keys.
At the same time, its integrated on-chain file storage system allows developers to attach encrypted, persistent data directly to smart accounts — enabling new use cases across DeFi, RWA, and DAO tooling. By reducing friction and improving reliability, Magmar equips developers to build applications that are easier to use, more secure, and better suited for long-term adoption.
